一种新型护坡结构的消能效果水动力学模拟

Hydrodynamic Simulation on Energy Dissipation of New Type Wave Slope Protection

针对废旧轮胎污染环境和钱塘江大潮"吃人"两个社会热点问题,结合了废旧轮胎二次利用的思路发明了一种防浪废轮胎护坡结构。新型的防浪废旧轮胎护坡结构在承受潮水冲击时,利用强水流在轮胎群错落结构的碰撞、旋绕中消减大量冲刷能量的消能原理,能够达到很好的消能防浪冲击效果。为了进一步比较这种防浪废轮胎护坡结构与现有堤防护坡结构相比所具有的优点,采用FLOW-3D进行水动力学数值模拟试验,试验结果证明,新型的防浪废轮胎护坡结构能够达到很好的消能防浪减缓冲击的效果。

Aiming at the two social issues of waste tires pollution and Qiantang tide hazard,based on concept of waste tires recycling,a kind of anti-wave tires slope protection structure was invented. When stricken by the tidal water,the new structure can cut back large amount of scouring energy when the strong water flow crashes and winds around among the tire groups to achieve a good effect of energy dissipation and wave resistance. In order to further compare the advantages of this anti-wave waste tire revetment structure with the existing dyke protection slope structure,FLOW-3D was used for the numerical simulation experiment of hydrodynamics. The experiment results prove that the new anti-wave waste tire slope protection structure can achieve a good energy dissipation and wave prevention.
